LEADING APPARATUS FOR MONOTYPE COMPOSING MACHINES.

Application filed September 28, 1926, Serial No.

The invention relates to an apparatus for type composing and casting machines, by means of which one or more leads are inserted between successive lines if required.

Apparatus of this kind is already known, in which the leads which are piled up hori-' zontally one above the other, are rotated through 90 during their movement and set up on the compositors or galley table;

apparatus is also known in which the leads are arranged vertically.

The apparatus according to the present invention belongs to the latter type of apparatus, in which the leads are set up on the galley table by the ascending and descending vertical movements of a leading plate. The apparatus, however, differs from the known machines by the fact that the leads are arranged side by side on edge on two lead holders adjustable with regard to their distance from one another and 'arranged on a movable slide.

In order that the invention may be fully and readily carried out, one form of the leading apparatus for type composing machines according to the invention is described hereinafter, by way of example, illustrated in the accompanying drawing.

Figure 1 represents a plan View.

Figure 2 represents a longitudinal front view, the support 16 and the leads-holder 8 not being shown; the connecting arm 17 being cut at line AB and-the leading plate 24 being cut at C of Figure 1.

Figure 3 represents a side view of the right part of Figure 1.

In the drawings, 1 is a frame fixed on the plate 2 of a composing machine by means of a bolt (not shown) which passes through the superposed holes 3 bored in the plate 2 and the frame 1. The upper part of the frame 1 comprises a guide t into which is adapted to slide longitudinally a slide-rest 5 which can be secured to the frame 1 by means of a screw 6; the sliding of the sliderest 5 on the frame 1 enables the line channel of the composing machine to be set free and easily accessible when the said channel happens to be blocked and requires the intervention of the operator.

In the upper part of the slide-rest 5 is a dovetail groove 7 into which can slide, in the 138,249, and in Switzerland September 28, 1925.

same direction as the slide rest itself, a leadsholder 8 which latter has extending from its lower part a projection 9 provided with a screwed hole into which engages the rod of a regulating screw 10 provided with a controlling knob 11; a plain part of the screwed rod engages freely into a projecting part 12 of the slide-rest 5 and is firmly fastened axially in' relation to the projection 12 by means of collars 13, 13', in such a manner as to enable the leads-holder 8 to be moved in relation of the slide rest 5 by the rotation of the screwed rod 10.

The slide-rest comprises side projections 14, 1 1, which have dove-tailed grooves 15, 15 designed to guide transversely, a support 16 with the leads'holder 8' which rests upon it; the leads-holder 8 comprises a connecting arm 17 provided with a slot 18 in which engages a bolt 19 having a thumb nut 20; the leadsholder 8' also has a lateral extension 21 superposed on the connecting arm 17 and which passes through a slot in the side of the support 16; the leads-holder 8' is screwed on the support 16 by means of the screws 22, 22, which engage freely through a slot cut out in the vertical side of the support 16, these screws being screwed to the vertical side of the leads-holder 8'; in this way the leads-holder can be moved, to some extent parallel to the support 16.

The extension 21 is bored with a hole through which passes the bolt 19 so that by tightening thumb nut 20 the support 16 and the leads-holder 8 are secured to the connecting arm 17 when not so secured the leads-holder 8' moves together with the longitudinal movements of the leads-holder 8 which movements are given by the screw 10.

Owing to the slot 18 enabling the bolt 19 to move laterally, the space between the vertical sides of the leads-holders 8 and 8 can thus be regulated.

The slide-rest 5 and the support 16 comprise strips 23, 23 designed to guide a vertically movable leading-plate 24 which is also provided with coacting guides 25, 25.

The guiding strip 25 is fixed to the movable leading-p'late 24 while the guiding strip 25, overlapping the top of the plate 24, is able to slide thereon'and is fastened to it by means of the tightening screw 26, the head of the screw 27 as well as the stem of the screw 26 being displaceable in a horizontal slot 27 in the leading-plate 24.

Rectangular leads 28, 28, 28", placed side by side, are disposed on edge and rest at their ends upon the leads-holders 8, 8, the whole of the leads being thus disposed on a horizontal plane in such a way as to be arranged in alignment with the composition. The leads 28, 28, 28" are constantly pushed forward towards the inner side of the leading-plate 24 by means of a rod 29 to which is attached a support-plate 30; the rod 29 is guided by a tube 31 fixed to the frame 1, in the interior of which tube is a spring 32 that bears at one end on the tube 31 and at the other end on a pin fixed on the rod 29 in such a way that the latter is constantly forced longitudinally towards the leading-plate.

A hock 33 is hinged on the plate 30 and is adapted to engage a notch 34 in the vertical side of the leads-holder 8, so as to secure the support 30 in its extreme outward position.

The leading-plate 24 is provided on its outer side with a catch member 35 hinged at 36, and having its upper parts bent to form catches 37, 37 which pass through orifices in the leading-plate 24, in such a way as to project therethrough. The catches 37, 37 are designed to engage the leads 28, 28, 28, when the leading-plate 24 moves downwards; the projection of the catches 37, 37 can be regulated by means of the controlling screw 38 the end of which presses against the outer side of the plate 24; the regulating of the amount of projection of the catches is designed to enable leads of various thicknesses to be used; the screw 38 is kept pressed against the plate 24 by means of springs 39; these springs 39 are sufficiently sp'ringy as to allow the catches to move aside during the raising of the leading-plate 24, and the lead which is pushed against the leading-plate is prevented from being raised by means of a stop-plate 40 disposed above the leads 28, 28, 28". This stop-plate is fixed on the slide-rest 5 by means of the screws 41 and 41. a

The leading-plate 24 is fixed by screws 42 and 42 to a screen 43 which forms part of the composing machine that has an up-anddown movement. The screen 43 has for purpose, when' it is lowered into the galley 44, to separate the two lines of types, one being the formerly cast line 45 which has been drawn before the screen by a part of the composing machine, not shown, and the other line 46 that has just been melted. When the screen 43 is lifted the line 46 is pushed against the line 45 by a line-pusher 47, which is also part of the composing machine and having a reciprocable movement for the purpose of pushing the lines on the galley 44 intermittently as they are composed.

On the side of the slide-rest 5 and the support 16 are arranged levers 48 hinged at 49, the outer ends of which are intended to press the leads against the plate 24 when the latter is lowered. The lowering of levers 48 is limited by. means ofan appropriate contrivance so as to enable them to take such a position that they are able to guide the leads and to thrust them against the inner side of the leading-plate 24 when the said leads are successively drawn down by the leading plate 24 and fall upon the galley 44.

The leads 28, 28, 28 are guided laterally in their lowering movement'by the vertical guides 50 and 51; the guide 50 being formed by a metallic rule which is fixed on the inner side of the plate 24, while the guide 51 is formed on the inner side of the guide 25, the said side being sufficiently extended downwards so that it is able to guide the leads 28, 28, 28".

The working of the apparatus above described is as follows:

The leads 28, 28, 28 being pushed forward against the lead-plate 24 by means of the rod 29, the leading-plate at the same time down and draws the lead 28 by means of the catches 37, 37"; the lead 28, passes between the lateral guides 50 and 51. The screen 43 also moves down with the leadingplate onto the galley 44 as shown in dotted lines on Figure 2, that is to say, being disposed between the lines 45 and 46; at this moment the leading-plate is lifted and allows the line-pusher 47 to push the whole set of lines 46, 28 and 45 on the surface of the galley 44 in such a manner that the line 46 takes the position previously occupied by the line 45. The line-pusher 47 retires to its former position; the leading-plate 24 and the screen 43 again move down drawing with them the lead 28-which falls onto the galley 44 while a new line, pushed by a member of the composing machine, takes the position previously occupied by the line 46 and at this moment the screen 43 is again lifted and the line-pusher 47 works as described before.

The set of lines formed by the lines and leads thus placed side by side on the galley 44 is disposed in such a manner as to be in the horizontal prolongation of the whole of the leads.

Having now. particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is Leading apparatus for monotype composing machine, defined by the fact that it comprises a frame supporting a sliding-rest provided with leads-holders on which the leads are placed on an horizontal plan side by side, the leads being constantly pushed ing of the leading-plate has for result to towards a movable leading-plate animated draw at least one lead and to intercalate this 10 vertically of an alternative movement by the last between the formerly cast line and the screen 01 the composing machine, the movline pushed behind the screen of the compos- 5 able leading organ comprising clutches ing machine.
